This research aims to conduct an in-depth study of the reliability of the swap-type LiFePO4 battery bracket on an electric motorbike. The main focus of this research is to evaluate the extent to which this battery bracket is reliable in everyday use, especially when facing various operational conditions. The methodological approach used in this study is very comprehensive. It includes a series of experiments and direct field tests on electric motorcycles equipped with LiFePO4 swap-type batteries. These tests were conducted to simulate various conditions encountered during daily use and evaluate the bracket’s response. This study used three battery configurations: 24 Series 4 Parallel, 24 Series 5 Parallel, and 24 Series 6 Parallel. Reliability was calculated theoretically using an exponential reliability function, while experimental tests were conducted to measure the discharge duration and voltage stability under actual conditions. Theoretical calculation results show that the more cells are arranged in parallel, the higher the total reliability of the system. From the calculation results, 24 series 6 parallel configuration has the highest reliability compared to 24 series 4 parallel and 24 series 5 parallel. These results are supported by experimental testing, where 24 series 6 parallel shows a longer discharge duration and better voltage stability, indicating a more optimal system durability in long-term use. Thus, this study concludes that the 24 series 6 parallel configuration is the best option for improving the battery system’s reliability on electric motorcycles. .
